LOCK.

I To all whomitmay conoem:

Be it known that we, VILLIAM.G. MAR- TINEAU, CLAEENoE; R. MARTINEAU, and A.

BENJAMIN APPLER, each a citizen of the United States of America, thesaicl WILLIAM C. MARTINEAU and CLARENCE R. ,MARTINEAU each residing.in-thecity of Albany, county of Albany, and State of New York, and the said A. BE JAMIN AEPLER residing at the city of WVatervliet, county, of Albany, and

State or New York, have invented certain new and useful Improvements in Locks, of which the following is a specification.

Our invention relates, to looks, and the ob- .ject of our invention is to provide a lock especially adapted for use on sliding doors on a railway train, provided with a means for keeping the hasp on 'the staple; together withsuch elements :and combinations as are hereinafter more particularly set forth and claimed. We-accomplish these objects by means of themechanism illustrated in the accompanying drawing, in which:

Figure 1 is a perspective view of our lock in a closed position. Fig. 2 is a perspective view showing the hasp oflf of the staple.

Fig. 3 is a reverse plan view of the hasp,

showing its connection with the hasp plate. Fig. 1 is an enlarged plan view of the end of the hasp plate, with parts broken away, showing the place where the insertion of the hasp is made. Fig. 5 is a detail view of the curved end of the hasp. Fig. 6 is a section along the lines, 1.1, on Fig. 4. Fig. 7 is a detailview showing the end of the hasp ininto its hinging position therein.

on and taken off of the staple, C. In the 1 Similar letters refer to 8111111211" parts throughout the several views.

The hasp, A, is provided'with a series of openings, B, B, either one of which is adapt ed to fit upon the staple, O, depending upon whether the door is closed tightly or not.

The hasp is'provided with a curved shank,

D, and rounded-head, E, at the end thereof. Thehasp plate, F, isprovided at one end with a cup-shaped portion, H, into which the rounded head,E, of the hasp may be placed and rotate when the hasp is placed cup-shaped portion, H, there is an elongated slot, G, which will permit of the hasp, A,

being insertedtherethrough, all except the rounded head, E, thereon. As thus arranged, the hasp may be moved outward off of the staple and downward to assume a ver tical position held by the rounded head of the hasp in the hasp plate.

Above the staple we pivottwo buttons, J and K,'each provided with a arm, L,.M, adapted to rest against the opposite sides of the staple, C, as shown-in Fig. 1, and when the hasp is in thepositionshown in said Fig. 1, the buttons, J and K, resting against the opposite sides of the staple, it is appar- Patented Sept. 22, 1914. ,Applicationfiled May 15, 1914.

ent that the hasp is held onto the staple by the buttons. Any vibration or motion of the car, providing these are used on a car door, will tend to throw one of the buttons away from the staple and cause the other of saidbuttons to be kept close in contact with the staple. At the end of each of the'buttons, J "and K, we place the fingers, O and P, which when pressed toward each other will rotate the buttons, causing them to assume the position shown in Fig. 2, permitting of the removal of the hasp from the staple. A stop pin, R, is placed between and at the upper portion of the buttons, J and K, against which the fingers, O and P, will engage and prevent further opening of the buttons, as shown in Fig. 2.

Through the arm, L, M, which may be placed in contact with the staple, we place an opening, T, registering with the opening, 25, in the staple, through which openings, T and t, any locking member such as a wire,

U, as shown in Fig. 1, may be placed. serted through the opening in the end of the hasp plate and retained so as to be drawn We have shown the staple, C, and the but- ,tons, J and K, and stop, R, mounted upon a plate, V, the plate having a right-angled projecting portion, o, bolted to the door jamb, X. But we do not limit ourselves to this manner of attaching the staple or its connections.

The sliding door, Z, carries the hasp plate, F, but it is apparent that it is not neces sarily a sliding door on which our locking attachment is placed, and we do not wish to limit ourselves to any particular place, nor to the exact construction of our invention.

What we claim as our invention and desire to secure by Letters Patent is:

'1. The combination of a hasp; means for hinging the same; a staple adapted to be placed through the opening in the hasp; two buttons pivoted above and adjacent to each side of the staple, arranged to hang by gravity over the hasp and against the opposite sides of the staple, substantially as described;

2. The combination of a hasp; a hasp plate provided with cup-shaped portion and an elongated slot therethrough; a curved portion on said hasp so arranged that the hasp may be inserted through said elongated slot with the exception of said rounded end portion which is adapted to articulate in said cup-shaped portion; a staple upon which the hasp may be placed by causing the staple to project through the opening in the hasp; means on each side of the staple for engaging the hasp after it has been placed in position on the staple, preventing the accidental Withdrawal of the hasp from v the staple, substantially as described.

3. The combination of a hasp; means for hinging the same; a staple adaptedto pass through an opening in the hasp; depending 1 7 buttons adapted to pass over'the hasp land o signatures in presence of two witnesses.
